摘要(Abstract)：

喀斯特岩层铝土矿的主要特点是岩溶洞、岩溶水多,裂隙发育,岩层和泥层相夹等,这些特点使露天台阶爆破中出现较多的根底和大块。试验中通过采取一系列技术措施,如空气间隔装药、合适的孔网参数、孔底起爆、增加炸药密度及改进药包包装等,取得了良好的爆破效果。文中介绍了试验方法及试验结果的分析。
The Karst formation bauxi te is mainly characterized by more Karst cavities,a lot of Karst wate r and fissures,and interbedding of rock and clay These features resul t in more toe rocks and boulders i n bench blasting A favorable blast ing effect is gained through takin g some technical measures such as air spaced charges reasonable hole pattern pa rameters, hole bottom priming, i ncreased explosive density and imp roved charge packing The test meth ods and analysis on test results a re introduced in this paper
